(S02E03) "So you're setting me up on a blind date with a potential murderer?" - Torres

When I first heard about Lightman's Mexican holiday via Shawn Ryan's Twitter account, I had pretty high hopes for it because as he suggested, it should be a "fun one." I assumed it would just be Cal and Emily having a grand ol' time, making fun of cabana boys when they lied about being out of pineapple juice or dark rum. There was some of that, but Cal, who always needs something to do, ending up getting embroiled in a fairly interesting case. The problem? The case that Gillian and the rest of the team got caught up in was far more intriguing and Cal wasn't there to take part of in any of it. Well... sort of.
